- is a specification.

This invention relates to improvements in projectiles andmore particularly to a projectile designed primarily for the destruction of dirigibles, air-ships and air craft generally in time of war. Its object then is to produce a bomb which may be timed so that when its speed through the air is known it can be timed to explode at a given distance from its mortar. Novel means for setting or timing the bomb and for exploding the same through the operation of internal mechanism constitute further objects.

\Vith the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the appended claims and illustrated in the accompanying drawings which form a part of said specification and in which Figure l is a view partly in vertical section and partly in side elevation of my improved bomb.

responding parts throughout the several views.

The reference numeral 1 denotes the'shell provided with a removable .screw cap 2 and formed with an annular collar 3 which serves as a rest or stop for the outer edge of a cover 4 adapted to fit snugly upon the top of a powder reservoir 5 disposed within the shell '1 and spaced away from the inner periphery thereof to afford store space for shrapnel 6, the upper end of this shrapnel container being also closedby the cover 4. The cover 4 is formed with a perforation in alinement with a similar perforation in the base of a frame 7 secured'to said cap and a detonator 8 is arranged in said perforated portions in the plane of movement of a hammer 9 carried by an angular lever 10 pivoted to the frame 7 and formed with a depending ear 11 to which a spring 12 is secured that is carried bya lug 13 secured to the frame base.

The lever 10 in raised position,Fig. 1', is capable of releasable engagement with a crank 13 carried bythe frame, A discharge wheel 15 having peripheral teeth 14 is slidably keyed to a plunger shaft 16, formed with transverse perforations 17, 18, that carries a loose weight 19 and a fixed yoke 20 having flexible terminations capable of frictional engagement with said weight. The shaft 16 at its lower end rests in the recessed portion 21 'of a lever 22 which is pivoted in bearings 23 secured to the frame base and which operates between a pair of upright guides 24 also secured to said frame base, the end of the lever 22 being spaced away from the floor base by a coil spring 25.

'The lever 22, further, carries a dog 26 adapted for engagement with the teeth 27 of a large gear wheel 28 fast upon a shaft 29 journaled in bearings 30 carried by the frame, the teeth of said wheel being also in mesh with the teeth 14 of the discharge wheel 15 and with the pinion 31 fast upon a shaft 32 journaled in bearings 33 carried by the frame, said shaft carrying a spring 34 one end of which is secured to a bracket 35 carried by the frame base.

and is capable of engagement, as said wheel rotates, with the crank 13 to swing the same .lieved of the weight.

out of engagement with the lever 10 to permit the spring 12 thereof'to move the same toward the frame base and the hammer 9 into engagement with the detonator 8 to explode the powder in the reservoir 5. The outer periphery of the shell 1 is marked, as shown in Fig. 2, to denote the number of yards it is intended the projectile shall travel from its mortar previous to the explosion. First the speed at which the projectile will travel is determined by suitable experiments, and-the length of time required for a complete turn of the wheel 15 is also determined. It will be noted the shaft 32 is rotated by the spring 34 and said shaft rotates the pinion 31 which turns the wheel 28 which turns the said wheel 15. To set or time the bomb a handle 38 is placed in engagement with the finger 37 and shaft 16 to rotate thesame; said handle is provided with an indicator 39 which travels about the periphery of the shell with said handle, when the cap is removed, and which may be stopped opposite any of the marks 40 of said shell desired, to correspond to the point at which the explosion is desired, with relation to the mortar. With the yoke embracing the weight 19 the bomb as set and shown 1n Fig.1 is ready. The spring 25 yieldingly retains the weight 19 and shaft 16-and lever 22 in raised position. The cap 2 is now placed upon the shell and the latter placed in the mortar and fired. The impact which causes the ejection of the projectile from the mortar will force the weight out of the yoke, into the position shown in Fig. 11, and depress the lever 22 thus freeing .wheel 28 of dog 26 and starting the mechanism. It is not possible for the spring 25 to return the weight 19 and lever 22 to normal position after the projectile is dischargedfrom the mortar as the ends of the yoke will contract materially when re- When the wheel 15 which has been set in motion by the spring 34 and connection causes the finger 37 to contact with the crank 13* the charge will be exploded as previously described.

What is claimed 15 1. In a projectile comprising a powder reservoir, a frame carried thereb a springpressed hammer carried by said rame to explode the powder, means carried by said frame normally engaging said hammer to retain the same in inoperative position, a spring shaft journaled in said frame, a toothed wheel fast upon said shaft, a plunger shaft journaled in said frame, means associated with said plunger shaft and frame j whereby the former is yieldingly retained in adjusted relation, said means also engaging saidtoothed wheel to retain the same in set position, a second toothed wheel slidably keyed upon said plunger shaft and in mesh with the first named toothed wheel, a finger carried by said second toothed wheel for engagement with the said hammer-engaging means, and a handle adapted for releasable engagement with said plunger shaft to rotate the same to set the mechanism.

2. In a projectile comprising a powder reservoir, a frame carried thereby, a springpressed hammer carried by said frame to explode the powder, means carried by said frame normally engaging said hammer to retam the same in inoperative position, a

spring shaft journaled in said frame, a

toothed wheel fast upon said shaft, a plun- I ger shaft j ournaled in said frame, means associated with said plunger shaft and frame whereby the former is yieldingly retainedin adjusted relation, said means comprising a weight and poke, fast and loose respectively, on said sha t, said yoke normally engaging said weight, connection between said last named means and said toothed' wheel for normally retaining the latter in set position, a second toothed wheel slidably keyed on said plunger shaft in mesh with said first named toothed wheel, a finger carried by said first named toothed wheel for engagement with said hammer-engaging means, and a handle adapted for engagement with said plunger shaft to rotate and set the same.

3. In a projectile comprising a powder reservoir, a frame carried thereby, a springpressed hammer carried by said frame to e lode the powder, means carried by said frame normally engaging said hammer to retain the same in inoperative position, a spring shaft journaled in said frame, a

toothed wheel fast upon said shaft, a plunger shaft journaled in said frame, a welght and yoke, fast and loose. respectively, upon said first named toothed wheel, a finger carried by said wheel for engagement with the said hammer-engaging means, and a handle adapted to engage said plunger shaft to rotate and set the same.
